A synapse is the point where two neurones connect. The neurones do not make direct contact: there is a gap between them called a synaptic cleft. The nerve impulse must be transmitted across this gap. Chemicals called neurotransmitters conduct the impulses across the gap: these chemicals may facilitate the passage of the impulse or they may inhibit the passage of the impulse:
^ acetylcholine (Ach) facilitates the passage of an impulse ^ gamma-aminobutyric acid (GABA) inhibits the passage of an impulse.
